Useless Spark Plug for Automotive Engines

After I put it to the test, I found that this spark plug was a huge waste of money... It didn't improve the engine's performance and, in fact, it caused MISFIRES and reduced fuel efficiency. i had to replace it with a better quality spark plug which solved all the issues..

Pros
  • None
Cons
  • Reduced fuel efficiency and caused misfires.

SLOW shipping best for spark plugs

I ordered 4 individual plugs rather than a pack of 4 as they were cheaper in that sense - dumb. The first came in a month. The second came 5 days later. I have a delivery date of the 3rd which will ship 2 months after the original order was placed. I don't have a delivery date on the 4th. Who knows how long it will be. If you're like me and need 4, just buy the full set and don't mess around with a few bucks. As for the quality of the spark plugs, NGK makes good ones. For all races, I prefer…

Pros
  • Trivalent coating eliminates the need for anti-seize and corrugated fins to prevent failure
Cons
  • It's ok
